Yes, things are very real up here. Some are unfortunate accidents; other things are risk of being in the mountains. The incident where the Sherpa fell into the crevasse was totally avoidable. I have gone through the Khumbu Icefall four times now, once completely alone. I clipped into almost every fixed rope, which are many, most so that I would not fall into a crevasse, others so that my body could be found at the next fixed anchor should anything cut loose.
